Drain your mackerel, sort the meat, removing bones and skin. To your sorted meat add some sautéed onion and celery, bread crumbs, seafood seasoning and fresh whole eggs. Mix well. Form into dinner size cakes and fry until golden brown on each side.
Another use for your Mackerel is to add your fish to a pasta salad. Before adding the fish to your salad, drain the mackerel and pick out the bones and remove any skin you may find. This is for looks only as there is nothing wrong with bones or skin which you may find in canned fishes.
